Translocase of outer mitochondrial membrane 20 (TOMM20)

Target
TOMM20
Molecular classification
Mitochondrial import receptor, Mitochondrial membrane protein, Transporter
01

Overview

Translocase of outer mitochondrial membrane 20 (TOMM20) is a key receptor subunit of the translocase of the outer mitochondrial membrane (TOM complex), which facilitates the import of nuclear-encoded proteins into mitochondria[1][3]. TOMM20 specifically recognizes the N-terminal mitochondrial targeting sequences of precursor proteins and helps direct them to the mitochondrial matrix for further processing and function. Dysregulation or elevated expression of TOMM20 has been associated with several diseases, especially cancers such as thyroid cancer, and it is considered a crucial component for mitochondrial health and cellular energy metabolism[1][3][6].

Safety considerations

Impairment of TOMM20 or the TOM complex can cause mitochondrial dysfunction, which may lead to cell death or contribute to disease pathogenesis; targeted inhibition may risk broad mitochondrial impairment.
